IMPROVEMENT IN FASTENINGS FOR WIRE FENGES.'

TO ALL WHOM IT MAY CONCERN:

Be it known that` I, WILLIAM E. LOCKWOOD, of Philadelphia, lennsylvania, have invented a. Device for Tightening the Wires of Fences; and I do hereby declare the following to be a full, clear, and exact description of the same,

My invention consists of a. pulley, arranged for receiving the wire of a fence, and having :timmy-sided projection, between which and a shoulder on one of the brackets in which thepulleyturns is inserted a key for retaining the wire in a tightenedcondition, the whole being constructed and arranged substantially as described hereafter, andforming a cheap, simple, and el'ective device for tightening the wires of fences.

In order to enable others to make and use my invention, I will now-proceed to describe its construction i andoperntion, reference being had to the-accompanying drawing, which forms a part of. this specification, and

in which- Figurel is a perspective view of my device for tightening the wires of fences. Figure 2, a. front view of the same. Figure 3, a section on the line 1 2, iig. 2, and Figure 4 a section on the line 8 4, iig. 2. Similar letters refer to similar parts throughout the several views. A represents part of a fence-post, to which are secured theV two cast-iron brackets B and B', the small 'journal a of the pulley D turning in the'latter bracket, and the large journal b of the seme pulley turning in end projecting through the bracket B, and havinga. square terminution,for receiving a suitable winch or screwkey. On one side of the pulley D is a. projection, el, which, in the present instance, is of the hexagonal form represented in iig. 4, but which may have live, eight, or any other approprinte number` of sides, and ongthe bracket B, adjacent to this projection, is formed a shoulder, e, between which and one of the sides of the said projection intervenes a. key, E. An annular recess,f, is fo'rmed'in one side ofthe pulley, and in the periphery of the latter is made a hole, t, for admitting the endsl of the fence-wire G, which may be bent as shown in fig.

3, so as' to retain its'hold of the pulley.

After the wire hes been thus inserted into the hole of the pulley, the latter is turned in the direction ofthe arrow, figs. 3 and 4, and the wire thereby coiled round or partly round the periphery ofthe pulley', until it has been drawn suiciently tight, when the wedge or key E is inserted between one of the sides ofthe projection d of the pulley and the inclined shoulder e of the bracket'v B, thereby efeetually preventing the -recoil ofthe tightened wire. Should the wire, owing to u change of temperature, or through other cause, require to be tightened or loosened, this duty can be readily accomplished after the withdrawal of the key, E.

I claim as my invention, and desire to secure by Letterslatent- The pulley D, its many-sided projection d, when the said pulley is arranged to turn in the brackets B and B', or their equivalents, and is confined by a key, E, all substantially as und for the purpose-herein set forth.

AIn testimony whereof, Ihave signed my name to this specification, in the presence of tiro subscribing witnesses.
